C190 Biology (C190) – 150 Questions on Cells, Genetics & Ecology Exam Practice 2026 – Western Governors University

This document contains approximately 150 biology exam-style questions with correct answers, designed for the C190 Biology course at Western Governors University. It covers a wide range of foundational topics including cell structure and function, macromolecules, genetics, cellular respiration, photosynthesis, evolution, and ecology, as presented throughout pages 1–28 . The content is structured in a clear question-and-answer format, making it ideal for quick revision and concept reinforcement. The material provides a comprehensive and in-depth review of core biological principles, beginning with basic concepts such as atoms, molecules, and chemical bonds, and progressing into more complex topics like DNA replication, transcription, translation, and inheritance patterns. It also includes detailed coverage of cell biology (organelles, transport mechanisms, homeostasis), energy processes (ATP production, Krebs cycle, electron transport chain), and organismal biology concepts such as tissues, organ systems, and physiological regulation. Additionally, the document explores evolutionary biology and ecological interactions, including natural selection, genetic drift, biodiversity, trophic levels, and biogeochemical cycles. The inclusion of definitions, processes, and applied concepts ensures that students develop both theoretical understanding and the ability to answer exam-style questions effectively. This makes it particularly useful for mastering terminology and preparing for assessments that require recall and conceptual clarity. This resource is particularly relevant for students enrolled in: General Biology (C190) Introduction to Biology Life Sciences courses Pre-Nursing or Health Sciences programs Environmental Science or Ecology courses It is suitable for undergraduate students, WGU learners, and anyone preparing for biology exams or seeking to strengthen foundational knowledge in biological sciences. The content aligns closely with commonly used textbooks such as Campbell Biology and other introductory biology course materials used in university-level programs.
